Total organic carbon, organic phosphorus, and biogenic barium fluxes as proxies for paleomarine productivity
Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

Uranium concentrations and 238U/235U isotope ratios in modern carbonates from the Bahamas: Assessing a novel paleoredox proxy
In order to validate the use of 238 U/235 U as a paleoredox proxy in carbonates, we
examined the incorporation and early diagenetic evolution of U isotopes in shallow …
